Oth fx lower end r femr, subs for opn fx type I/2 w nonunion

This code describes a fracture located at the lower end of the right femur, excluding specific condylar or supracondylar types. It specifically indicates that the fracture is an open fracture of type I or II, meaning there is a wound communicating with the fracture site, and that the bone has failed to heal after a previous treatment attempt (nonunion).

Use this code for a patient presenting for follow-up care of an open fracture of the distal right femur that has not healed. This applies when the initial injury was an open fracture classified as type I or II, and the current encounter addresses the ongoing nonunion.

• Ensure documentation clearly specifies the fracture location as the lower end of the right femur, excluding condylar or supracondylar.
• Verify that the original fracture was an open fracture, type I or II, and that the current encounter is for nonunion.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
